`department` column has been eliminated from `Principals` column family. We are not asking for this to the users, therefore we won't store it in Cassandra. However, is still a required field by SAFE when creating a user, so we would input the tenant alias to SAFE
I modified the functions in shared/oae/api/oae.api.admin.js which call the oae-principal endpoints in Hilary in order to create a regular user of a tenant admin. So now, these functions include the private and public ssh key generated when the user is created.
I decided to moved a tag to my widget instead of having it in the shared tags.
* I removed from the left hand menu the item that calls the widget that shows the projects and groups, as it is an old experiment we are not going to use.
* I changed the name to the widget (and to the left hand menu item) that list projects and has a button to call the widget than creates project. Now is called `Project management`
* Changed the left hand menu of `/me` page, now there is only two items: "My projects" and "Queues" (they point to their two corresponding widgets: `mysafeprojects` and `queues`).
* Added the page `/sgroup`, it have two items in its left hand menu: "Files", "MyJobs", "Members" (they point to their corresponding widgets: `tablesfs`, `myjobs` and `sgroupmembers`).
